@drshahzadiharper: What are the common side effects of GLP-1 weight-loss injections? The most common early symptoms include feeling cold, tiredness, palpitations, headaches, nausea, sulphur-type burps, bloating and constipation. For most people, these settle within 24–48 hours, especially if you start on a low dose and gradually build up. GLP-1s shouldn’t make you feel unwell long-term — the key is starting slowly and being medically supervised. Questions? Drop them below or email [email protected]
